Aluminium windows and doors guaranteed to save you money

Whether it’s panoramic windows with a spectacular view, triple glazed windows to keep the warmth in on a winter's night or a bespoke sliding door to add to your house, we offer a 10 year guarantee on all our systems. So now you can rest assured that each system has been designed to meet the highest technical specification and standard for your country.

Our 10 year guarantee covers:

  • Aluminium profiles (Extruded and Rolled)
  • Lacquer or anodisation layers
  • Insulation

Aluminium profiles

We cover both extruded aluminium and rolled aluminium ensuring that they both meet industry standards.

Standards extruded aluminium:

  • Composition to standard EN 573 parts 3 and 4;
  • Mechanical properties to standard EN 755 part 2;
  • Tolerances to standard DIN 17 615 and EN 12020 part 2;

Standards rolled aluminium:

  • Composition painted aluminium EN AW 1050 A H24 to standard EN 573 part 3;
  • Composition anodised aluminium EN AW 5005 H14 AQ to standard EN 573 part 3;
  • Mechanical properties to standard EN 485 part 2;
  • Tolerances to standard EN 485 part 4.

Painting and anodising

Our 10 year guarantee also covers lacquer or anodisation layers so you don’t need to worry about wear and tear to your new windows or doors. As aluminium is a soft metal, anodisation provides an extra level of protection. The anodisation of aluminium is a process that results in a much harder external layer that works to strengthen parts like pistons so that the parts last much longer, saving you money in the long run.


No one likes the cold weather to creep into their homes, which is why our 10 year guarantee is particularly good for triple glazed and bifolding triple glazed windows. We ensure adherence between the polyamide strips and the aluminium; and we preserve the thermal and mechanical properties of the insulator, within the boundaries defined by the technical specifications.
